Can pp based film improve energy storage density?

Recently, T. C. Mike Chung et al. reported that the energy storage density of PP based film could be significantly improved by using specially designed PP copolymer or cross-linkable PP copolymer [, , ].

What is the energy storage density of biaxially oriented polypropylene (BOPP) film?

Although Eb seems to be the most critical parameter in determining Um, the biaxially oriented polypropylene (BOPP) film with a high Eb of 600 MV/m, the state-of-the-art commercially available dielectric polymer, can only exhibit an energy storage density of 1-2 J/cm 3 due to the low intrinsic ε (2.2) of PP [11, 12].

Does pp grafting improve energy storage properties?

What’s more, the grafting of PS significantly improved the high-temperature energy storage properties of PP. At 110 °C, the discharge energy density of the PP- g -PS (8%) film is 3.44 J/cm 3, which is 93% higher than that of the PP film (1.78 J/cm 3). And at the electric field strength of 440 MV/m, the efficiency still exceeds 96%.

Is polypropylene a good energy storage material?

Cite this: ACS Appl. Polym. Mater. 2024, XXXX, XXX, XXX-XXX With the development of modern power systems, advanced energy storage polymer films are receiving attention. As an important energy storage dielectric material, polypropylene (PP) film has the advantages of low dielectric loss and high charge/discharge efficiency.

Why do polymeric film capacitors have a high energy storage density?

However, the development of film capacitor towards high energy storage density is severely hindered by the low dielectric constant (ε) and low charge-discharge efficiency (η) of the polymeric films. The film of polypropylene (PP), the most used polymeric film with a market share of 50%, owns a high η due to its low inherent hysteresis loss.
